  • Publication number: 20210201756
    Abstract: A display driving apparatus includes an output control circuit configured to, with one frame being divided into a plurality of blank periods by touch driving, output source signals corresponding to display data during the plurality of blank periods; and a polarity control circuit configured to receive pre-polarity control information for polarity inversion, and control polarities of the source signals outputted from the output control circuit, for polarity inversion by the unit of vertical 2 dots for one frame, wherein polarities for pre dummy lines and active data lines of odd-numbered and even-numbered blank periods are controlled by the pre-polarity control information.
